yes, that's been a known issue.  Since X/Open says curses.h defines bool,
and C++ defines bool, I attempt to make the types coincide.  You don't
have to _build_ ncurses with a C++ compiler, but it has to be available
for configuring.  Note that internally ncurses uses NCURSES_BOOL, but
I haven't found a good argument for making it visible in curses.h -- only
the corresponding definition of 'bool'.

not really (gcc 3.[0-9] will provide enough variety)
